At launch, the long-awaited (and much hyped) western adventure that is Red Dead Redemption 2 is only available on the PS4 and Xbox One.

That might not be the case forever, though. Code hidden within the game’s mobile companion app suggest that a PC version could be in the works.

Last week, we wrote about Red Dead Redemption 2’s companion app, which lets you rip the in-game map off the TV and put it on a nearby tablet, instead. No more pausing just to figure out if you and your horse are still headed in the right direction.

Some tinkerers over at GTAForums (as spotted by RockstarIntel) have been poking around that very app, and have unearthed a few interesting parameters left behind.

Two unused parameters tucked into the app (“PARAM_companionAutoConnectIpPC” and “CommandIsPcVersion”) mention the PC platform by name, but there are also dozens of different parameters referencing advanced graphic settings that generally don’t exist on consoles.

While the original Red Dead Redemption never made it beyond the console, this wouldn’t be Rockstar’s first foray into the PC world. Many of their most popular games landed on PC… eventually. GTAV, for example, launched on consoles in September of 2013 and made its way to Windows in April of 2015. L.A. Noire shipped for consoles in May of 2011, and hit PCs near the end of the same year.

Adding fuel to the fire: a few months back, a mention of a PC build reportedly popped up in a Rockstar designer’s LinkedIn profile.

With all that said: as with all things relating to video game releases, don’t get your hopes up too high until you hear it straight from the developer’s mouth. While the signs point to a PC build having existed in some form at some point, there’s always the possibility that these parameters are left over from the company’s own internal testing, or that plans will change.
